Copy letter from Robert William Frederick Harrison to Dr E F Russell, Rothamstead Experimental Station, Harpenden, Herts 'In answer to your enquiry, I beg to inform you that we do not possess the book you ask for "Analysis of steel works materials" by H Breasley & F Ibbotson. Possibly the Chemical Society might have it, though it does not appear in their 1903 catalogue. May I say that, under the Library REgulations (a copy of which I enclose) I can hardly send books to the Station without a letter from a Fellow of the Society, authorising me to do so on his responsibility.' 11 March 1913
